我的阿里云服务器上本来搭了一个uwsgi+django的环境，用nginx代理，但是现在需要再搭一个tornado，用supervisor监控，在nginx配置里分配了一个url，django为根url，现在情况是tornado的url都是404 not found

贴nginx的conf:

    upstream bus-server {
        server 127.0.0.1:8001;
        server 127.0.0.1:8002;
        server 127.0.0.1:8003;
        server 127.0.0.1:8004;
    }

    server {
        listen       80 default_server;
        # listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location /bus {
            proxy_pass http://bus-server;
            proxy_pass_header Server;
            proxy_set_header Host $http_host;
            proxy_redirect false;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Scheme $scheme;
        }

        location /static {
            alias /root/aqi/static;
        }

        location / {
        include uwsgi_params;
        uwsgi_pass 127.0.0.1:9090;
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }

求助大神帮忙解决一下！！！感激不尽！
